Wintering afloat

[Guest]

We try to use our boat for a many weekends as possible all year round which of course leads to careful frost protection during the unoccupied times and I would welcome some advice on whether the "domestic" water tanks best left full or low?

Complete draining/refilling and removal of airlocks is a bit of a pain on a weekly basis!

Leave them low, then if they freeze, ice expansion wont burst the tanks. leave the taps open, then if they freeze, it will help to prevent burst pipes.

Personally I would drain water heaters and electric pumps where they are above the water line or when on a drying mooring. Most items below the water line seem to be ok unless we have an extremly cold spell. If in doubt though drain all, it is cheaper than buying new items!

A couple of years ago I had a Pegasus 800 on a drying mooring - the fuel waxed the water tank froze - all thawed out OK.

I know it's a pain but it is always best to drain the system and leave the taps open. Don't forget the most vulnerable part - the pump. Either release the screws at the base to ensure all the water has been drained or fit a tubular heater close to it coupled to a frost protector thermostat. Don't forget to protect the accumulator tank if fitted.
I would leave the system in this protected state and use a large food grade water container during the winter months - all the camping stores have them and they are dirt cheap. Plus the water is always fresh!!
